ISDN Simulator - sources in B channels
The sources are shared between:
- permanent connections (Data Link, TRANSDATA, TRANSIT or the two Cofidec
interfaces). The permanent connections are initialized upon profile launching and set
for the entire duration of the profile.
- switched connections established by the Q931 simulator for outgoing and incoming
communications.
The sources are allocated firstly to permanent connections and then are dynamically
shared between switched connections.
If the source is not available at the time of the switched connection to the B channel,
the communication is cleared by the emulator.
On switched connections, the sources, depending on their type, are connected to B
channels independently during the first state (establish state) and the second state
(active state) of the communication:
- establish source: connected during the establish state as soon as the B channel
has been identified (mainly for broadcasting the dialing tone).
- active source: connected during the active state.
A set of common sources is available for switched connection to the Time-Slots .The
sources are for multiple connection or single
connection:

The simulation dialogue provides also access to the analog sources:
- directly for Handset and I/O Analog (using the first Cofidec available,
Cofidec 1 if not used permanently, otherwise Cofidec 2)
| ANALOG SOURCES |
| Designation |
|
Connection to TS |
| Handset |
|
Cofidec -> All TS; 1 TS -> Cofidec. |
| Analog 1 |
|
Cofidec -> All TS; 1 TS -> Cofidec. |
| Analog 2 |
|
Cofidec -> All TS; 1 TS -> Cofidec. |
- indirectly by Cofidec output for broadcasting on several communications of the
analog source connected to the Cofidec via the analog matrix connection.
- Example of configuration for simulation of both directions of a TS:
- Cofidec 1: analysis on Input direction.
- Cofidec 1: simulation (implicit Output direction).
